Excellent thermal wear for cool/cold weather hunting. Primarily, I hunt in Ohio/Indiana. Temperatures between 20-40 degrees. This is an excellent base or layer for warmth. I wear Under Armour Coldgear as a base layer, I wear this over my Coldgear. Works excellent! I have decreased the bulkiness of multiple layers. Very warm. Additional benefit is scent control with silver. Great for treestand hunting. Too warm if much walking. Get one size larger than usual if using as layering. Also, works great as intended as a base layer.

This is for the stand hunter. I own each of the UA brand base layers and this is definately the warmest. The only issue I have with it is if you worn any of the other UA base layers you'll want to order this one in the next size up, or even 2 sizes up, as the Treestand base does not stretch to fit like the others.
